I came across this Exeter based business on Facebook and can't speakers highly of it!
Iittle trees handmade makes baby and chdrens goods. I bought one of their chalk mats which is basically a portable chalk mat with a handy pocket to store chalks in also the other side can be used as a placemat. My daughter loves hers and it is a permanent fixture in my bag now! If you need something to keep your little one busy I say get one you won't regret it.
